Regular Expression Question

I want to match insert statements that have a select clause instead of a values clause. (i.e. "insert into... select * from ..." but not "insert into ... values(...)"

I use the following regular expression:
\binsert\b(?:.|\n)+?(?!values)\bselect\b

I thought that the (?!values) would tell the parser to stop if it hit the string "values", but perhaps I do not fully understand negative lookaheads...

Is there any way I can accomplish my goal?

BTW, disable smilies unless you want some weird looking regular expressions ;)

Could you elaborate?

Transact SQL (and perhaps ANSI SQL) allows for at least two versions of the INSERT statement.

Insert [into] table1 (column1, column2, ...) values (value1, value2, ...)

and

Insert [into] table1 (column1, column2, ...) select columnA, columnB, ... from tableA

I was trying to build a regular expression that would match the second type of INSERT statement, but not the first.
